A new study from researchers in England found that the secret to zapping a cigarette craving is as simple as a little exercise. No, you don't have to go on a 5-mile jog, just a walk around the block can help.

The researchers combed through 19 past studies and found and interesting takeaway: those who did something active when a cigarette craving cropped up were more likely to beat it than those who were inactive (think, sitting at your desk or watching TV).
